Recovering Audio Files in BIAS Peak

Sooner or later, despite your best efforts, you’re going to discover that the audio file that opened perfectly yesterday now won’t open at all. Who knows where the corruption came from — all that matters is that you can recover what may have been a brilliant piece of music or a once-in-a-lifetime performance. Fortunately, BIAS Peak comes with a tool called Recover Audio Data. This extracts audio data only, ignoring other information like the file’s header, loop points, Region markers and so forth. These are places where corruption can occur that makes your Mac think the whole file is messed up.

There are a few things that Peak needs you to tell it in order to successfully recover the audio, such as the number of channels, the file’s bit depth and sample rate, the audio data location and the byte order. With these bits of information and depending upon the actual amount of damage (not to mention a little luck), Peak may be able to recover audio files which, in the past, were unusable. But again, you must be able to provide the necessary data regarding the format the file was recorded in, otherwise you may end up with four minutes of white noise.

When the Recover Audio File tool encounters corrupt sectors with media, file or I/O errors, it will attempt to recover all the audio data it possibly can and will then place it into a new audio document. If it cannot recover certain data, it will simply write those sections as silence, so you won’t end up with the digital equivalent of fingernails on a blackboard.
